Amazon S3 Watcher

Automation Workshop features a remote file monitoring module—Amazon S3 Watcher. It scans a folder in AWS S3 bucket for file changes. It does not require AWS Transfer for SFTP Service to be enabled in the AWS Console, however it is possible to monitor such Amazon Simple Storage Service that has the SFTP Service enabled using SFTP Watcher.

Amazon S3 Watcher can launch a Task when a file or folder is created, modified, deleted in the remote bucket. It can also watch for the number of files in a directory, and look when a file reaches a certain size limit. A file mask filter allows monitoring for selected file types or files with specific names.

Amazon S3 Watcher Trigger is part of a Windows Automation solution—Automation Workshop. It allows monitoring AWS S3 on your premises (self-hosted solution) without depending on online services.

Automation Workshop has built-in more than a hundred Actions that can do a multitude of tasks on your files, such as download or upload files, synchronize whole directory trees, compress files, send emails, and much much more.
